3 BASIC OPERATION14D Setting subaudible tones forrepeater useSome repeaters require subaudible tones to be accessed.Subaudible tones are superimposed over your normal signaland must be set in advance.➀ Push [VFO] to select VFO mode.➁ Push [BAND] to select VHF or UHF.➂ Push [(H/L)SET] for 1 sec. to enterset mode.➃ Push [TONE] or [H/L] several timesuntil “rT” appears.➄ Rotate [DIAL] to select the desiredsubaudible tone.➅ Push [(VFO) CLR] to exit set mode.• Available subaudible tone frequencies (unit: Hz)TTUSING SET MODE D Setting an offset frequencyWhen communicating through a repeater, the transmit fre-quency is shifted from the receive frequency by an amountdetermined by the offset frequency.➀ Push [VFO] to select VFO mode.➁ Push [BAND] to select VHF or UHF.➂ Push [(H/L)SET] for 1 sec. to enterset mode.➃ Push [TONE] or [H/L] severaltimes until “OW” appears.➄ Rotate [DIAL] to select the desiredoffset.• Selectable steps are the same as thepre-set tuning steps.• MHz step may be helpful for large frequency changes—push[(VFO)MHz] for 1 sec.➅ Push [(VFO) MHz] to exit set mode.
